Frequently Asked Questions
Does Blue Titanium look different on a rifle versus a pistol upper?
Yes — the longer upper and 12″ handguard give the finish significantly more surface area to show. The metallic undertone that shifts between silver and blue-purple depending on light is more prominent on a full-length build. If you’ve seen the Blue Titanium pistol kits and liked the color, the rifle upper reads as a more substantial version of the same finish.
What’s included and what’s not?
Included: Blue Titanium Cerakote stripped upper receiver, 16″ barrel, 12″ KeyMod handguard, carbine-length gas system, A2 flash hider with crush washer, dust cover with door hardware, mil-spec forward assist, low-profile gas block, and stainless steel gas tube. Not included: bolt carrier group (BCG) and charging handle — both available as add-on options on this product page.
What lower receiver does this fit?
Any standard mil-spec AR-15 lower. The upper uses mil-spec 7075-T6 aluminum with standard M4 feed ramps and threading.
What gas system length does this use?
Carbine-length — standard for 5.56 NATO on a 16″ barrel.
Can I swap out the A2 flash hider?
Yes. The barrel is threaded 1/2″×28. Unthread the A2 flash hider and install any compatible 1/2″×28 muzzle device — suppressor mount, compensator, or brake.
